Brief Summary:

This is a nonrandomized, fixed-sequence, open-label study to evaluate the effect of a single dose of fedratinib on the PK, safety, and tolerability of single doses of digoxin, rosuvastatin, and metformin in healthy subjects. The subjects will participate as follows:

  • Screening phase
  • Treatment phase (includes baseline)
  • Follow-up telephone call Subjects will be screened for eligibility during the screening phase. Subjects who meet all inclusion criteria and none of the exclusion criteria will return to the clinical site on Day -1 for protocol-specified assessments, and will be domiciled at the clinical site from Day -1 through the morning of Day 22.

During the study, blood samples will be collected at prespecified times for PK and PD. Urine samples will be collected at prespecified times for urinary PK evaluation of metformin. Subject safety will be monitored throughout the study.

Arm Intervention/treatment
Experimental: Treatment Administration

All subjects will receive the following oral doses of IP following an overnight fast in the fixed-sequence below:

  • Day 1 (Period 1): 1 × 0.25-mg digoxin tablet, 1 × 10-mg rosuvastatin tablet, and 1 × 1000-mg metformin tablet.
  • Day 7 (Period 2): 6 × 100-mg fedratinib capsules PLUS (after approximately 1 hour from the time of fedratinib administration) 1 × 0.25 mg digoxin tablet, 1 × 10-mg rosuvastatin tablet, and 1 × 1000-mg metformin tablet.
Drug: Fedratinib

Drug: Digoxin

Drug: Rosuvastatin

Drug: Metformin

Primary Outcome Measures :
  1. Pharmacokinetic - Cmax (Digoxin, Rosuvastatin and Metformin [ Time Frame: 96 hours ]
    Maximum observed plasma concentration

  2. Pharmacokinetic - AUC (Digoxin, Rosuvastatin and Metformin [ Time Frame: 96 hours ]
    Area under the curve

  3. Pharmacokinetic - CLr [ Time Frame: 48 hours ]
    Renal Clearance

  4. Analysis of Glucose AUC after OGTT using linear trapezoidal method [ Time Frame: 3 hours ]
    Area under the curve

Secondary Outcome Measures :
  1. Adverse Events (AEs) [ Time Frame: From the time the ICF is signed until study completion and up to 30 days after the last dose of IP ]
    An AE is any noxious, unintended, or untoward medical occurrence that may appear or worsen in a subject during the course of a study. It may be a new intercurrent illness, a worsening concomitant illness, an injury, or any concomitant impairment of the subject's health, including laboratory test values, regardless of etiology. Any worsening (ie, any clinically significant adverse change in the frequency or intensity of a pre-existing condition) should be considered an AE.

  4. Female subjects NOT of childbearing potential must:

    a. Have been surgically sterilized (hysterectomy or bilateral oophorectomy; proper documentation required) at least 6 months before Screening, or postmenopausal (defined as 24 consecutive months without menses before Screening, with a follicle-stimulating hormone [FSH] level in the post-menopausal range according to the laboratory used at Screening).

  5. Females of childbearing potential (FCBP1) must:

    1. Have a negative pregnancy test as verified by the investigator at Screening and Baseline (prior to starting study treatment). She must agree to ongoing pregnancy testing during the course of the study, as applicable, and after end of study treatment. This applies even if the subject practices true abstinence from heterosexual contact.
    2. Either commit to true abstinence from heterosexual contact (which must be reviewed on a monthly basis, as applicable, and source documented) or agree to use, and be able to comply with, any one of the following highly effective contraception methods without interruption, beginning at least 14 days prior to starting investigational product (IP), during the study treatment, and for at least 30 days after the last dose of IP. - Intrauterine device (IUD; non-hormonal only); tubal ligation; or a partner with a vasectomy. The chosen form of birth control must be effective by the time the subject receives the first dose of IP.
  6. Male subjects must:

    a. Practice true abstinence from heterosexual contact (which must be reviewed on a monthly basis, as applicable, and source documented) or agree to use a barrier method of birth control (condoms not made from natural [animal] membrane [latex condoms are recommended]) during sexual contact with a pregnant female or FCBP while receiving study treatment, and for at least 30 days after the last dose of IP, even if he has undergone a successful vasectomy.
